Can you be more specific? What is it that you want, have you tried anything already, what were the errors, etc.

In general, you can cross-compile using xplatform passed to configure. See configure --help for more info.

You usually don't need to modify any files. In rare cases, you may need to touch mkspecs for your toolchain.

In general:

download source code of Qt (tar.bz package)

extract it and cd into it

run ./configure -prefix $PWD/qtbase -xplatform <your mkspecs> <other options>

make

ready! You can now compile your application using this Qt version

As for the choice, you probably need to go with arm-linux-g++ if your target platform is ARM-based. But I can't say more without hearing more details from you ;)

got this error:

Creating qmake...
make: Nothing to be done for `first'.

Warning: Disabling pkg-config since PKG_CONFIG_LIBDIR is not set.

No QPA platform plugin enabled!
If you really want to build without a QPA platform plugin you must pass
-no-qpa-platform-guard to configure. Doing this will
produce a Qt that can not run GUI applications.

Your error message is self explaining. Isn't it?

bq. No QPA platform plugin enabled! If you really want to build without a QPA bq. platform plugin you must pass -no-qpa-platform-guard to configure. Doing this will produce a Qt that can not run GUI applications. The dependencies needed for xcb to build are listed in src/plugins/platforms/xcb/README
